Answer:

The value is $P_{max} = 2.11 * 10^{6} \ W$

Explanation:

From the question we are told that

The maximized electric field strength is $E = 3.0 \ MV/m = 3.0 *10^{6} \ V/m$

The diameter is $d = 1.5\ cm = 0.015 \ m$

Generally the cross -sectional area is mathematically represented as

=> $A = \frac{\pi * d^2 }{4}$

=> $A = \frac{3.142 * 0.015^2 }{4}$

=> $A = 0.0001767 \ m^2$

Generally the maximum power is mathematically represented as

$P_{max} = \frac{E_{max}^2}{ 2 * \mu_o * c } * A$

Here c is the speed of light with value $c = 3.0 *10^{8} \ m/s$

$\mu_o$ is the permeability of free space with value $\mu_o = 4 \pi *10^{-7} \ H/m$

$P_{max} = \frac{ (3.0 *10^{6})^2}{ 2 * (4 \pi *10^{-7}) * 3.0 *10^{8} } * 0.0001767$

=> $P_{max} = 2.11 * 10^{6} \ W$

What property is used to distinguish the layers of the atmosphere?

Margarita [4]

There are many porperties. You can use Altitude, Temperature, Pressure and Density, but the best one is temperature. The resaon for that is that based on the temperature changes then the athmosphere can be broken into four major layers. Remember that the layers are the following: <span>the </span>troposphere,the<span> </span>stratosphere, <span>the </span>mesosphere<span>, and the</span>thermosphere<span>.</span>
